AUXLIARY APPARATUS FOR SUPPLYING STEAM TO RADIATORS.

Specification of Letters Patent.

Patented April 17', 190e.

Application led November 25, 1904:. Serial N0. 234,165,

- which the following isa specification.

. the pipe b. In this Way the auxiliary heater My invention relates to certain new and useful improvements in auxiliary apparatus for supplying steam to radiators; and its object 1s to produce a devicel of'this class Awhich shall have certain advantages which will appear in the course of this speciiication. A

To this end my invention consists in certain novel features which are shown in the accompan g drawings as embodied in my. preferred Edil in of construction.

In the aforesaid drawings, Figure 1 is an elevation of my improved device. 'Figi' 2 isa central longitudinal section in the line 2 2 of Fig. 3. Fig. 3 is a transverse section in the line 3 3 of Fi 1, and Figs. 4 and 5 are vertical longitucIinal sections through the connecting-boss of a radiator and illustrate two forms of a plug used inconnection with this device.

Referring to the drawings, A is the end coil of an ordinary radiator, such as is made up of sections provided with' bosses, by means of which each section communicates with the other to permit ofthe passage of the steam. My object is to provide an auxiliary heater which can be connected to such a radiator by means of a pipe or pi es opening directly into the boss of the en section opposite the end in which the steam-pipe from the ordinary supply enters. rious attempts have been made to suppl radiators with auxiliary heaters, but in eac instance a special radiator has to be employed to be used in connection with the auxiliary heater. B is a suitable boiler arranged partly above and partly below the bottom of the steam-s ace within said coil. Said boiler is connecte with the radiator by means of a steam-pi e b', leading from the boiler and threadedpin the boss upon the end section of the radiator, and a return-pipe b also con nects the boiler with said boss. The steam enters the radiator through the pipe b', and the water of condensation returns through I am aware that vamay be connected to the radiator by merely threading the inlet and outlet steam pipes in the bosswhich is already provided with an opening which under ordinary conditions is cosed up by a plug. Figs. 4 and 5 show the boss, Fig. 4 showing the opening therein of considerable. diameter. For this reason said opening is closed by a large plug a, which m turn is bored and tapped to receive smaller plugs a a2, "whichpluvs may be remved to receive the pipes b it. In Fig. 5 the original opening in the boss is quite small, and inthis' case a second opening is made above the original opening, b'oth of which openings may be closed by plugs a3 a4 when lthe radiator is used without the auxiliary heating device, but which are removed and the pipes b b threaded in said openings when the auxiliary heater is used. The boiler is provided with-a water-gage b2, having a cock b3, by which the contents of the boiler can be removed, and with a plug b4, by which the boiler can be iilled, if necessary.

Immediately below the boiler is a heaterbox C, having perforated ends and sides for the admission of air, but with a closed bottom. The heater-box may he secured to the boiler b means of clips c2, as shown. The side walis and especially the bottoni are protected by asbestos to get the greatest heating effect without much radiation. One end of the heater-box C is provided with a conical opening c, from which extends a pipe C', having nipples c', adapted to direct gas against the bottom of the boiler. A gas-pipe D is arranged to discharge a jet of gas through the conical o ening c of the heater-box, thereby mixing t e same with air, and into the pipe C. Below the heater-box C is supported a water-pan E, which serves the double purpose o supplying aqueous vapor to the atmosphere and of protecting the floor beneath the structure from the influence of the heat given 0H by the heater-box.

The o eration of my improved device will be read' y'apparent. When there is no steampressure in the radiator system, it is frequently desirable to generate a small amount of heat, and for this purpose my device is particularly designed. When so used, the main valve of the radiator is cut off and the gas turned on and lighted in 'the heater-box.

then be generated in the boiler,

IOO

which will low into the radiator and warm the room. My device has a further advantage that it is in constant communication with the radiator and that the boiler is situated partly below the level thereof, so as to:

form a trap for the water of condensation'. The boiler should in practice be kept full of water to approximately the level shown in the drawings, and it will rarely be found necessary to fill theboiler, as the water of condensation will keep it filled to the proper level. The water can be drawn off through the cock b3.

Irealize that considerable variation is possible in the details of this construction without departing from the spirit ofthe invention, and I therefore do not intend to limit myself to the specific form herein shown and described.

I claim as new and desire to secure by Letters Patent- 1. In a device of the class described, the

i ew'. .:-'S'-` combination with'a radiatbi having the o rdinary connecting-boss, of 'an auxiliary heatln boil/er having supply and return pipes .threa ed in said boss and means for heating the water in said auxiliary boiler.

` 2. In a device of the class described, the

combination with a radiator rovided with the usual connecting-boss, olP an auxiliary heating-boiler, a -steam-suppl pipe and return-pipe connecting therewltlh7 and threaded in said boss, a heater-box below the boiler and a burner within said box for heating the water within the boiler.

In witness whereof I have signed the above application for Letters Patent at Chicago, in the county of Cook and State of Illinois, this 21st day of November, A. D. 1904.
